Orontids of Commagene
In Nemrut Dagi, opposite the statues of Gods there are a long row of pedestals, on which stood the steles of the Greek ancestors of Antiochos. At a right angle to this row stood another row of steles, depicting his Orontid and Achaemenid ancestors. From these steles the ones of Darius and Xerxes are well preserved. In front of each stele is a small altar. Inscriptions have been found on two of those altars. Much attention was given by Antiochos that everyone would be aware that he was related to the dynasty of the King of Kings, Darius I, by the marriage of princess Rhodogune to his ancestor Orontes. The father of Rhodogune was the Persian king, Artaxerxes. In 401 BC he defeated his younger brother, who tried to throw him from his throne. Because of the help Artaxerxes received from his military commander and satrap of Armenia, Orontes, he gave his daughter in marriage to him. Their descendant, Orontid Mithradates I Kallinikos married Seleucid Princess Laodike Thea Philadelphos.
